Automobile-Jacks, of which the following is a. specificatiomreferencebeing had to the accompanying drawings.

This invention relates to improvements jacks and particularly toimprovements in jacks for supporting automobiles having a i a swingingmovement body; and Fig. T is a detail broken axle (either a. front orrear axle);

and an object of this invention is to an automobile jack construction,facture, easily applied and efficient, handy venient in operation anduse.

In the drawings illustrating the principle of this invention and thebest mode now knownto me of applying that principle, Figure 1 is an.elevation showing my new jack applied to an automobile having a brokenrear axle; Fig. 2 is a, similar view showing my new jack applied to'anautomobile having a broken front'axle; Fig. 3 is an elevation of my newjack showing the three-part hinged construction of the same; Fig. 4 is aplan view; Fig. 5 is a central longitudinal section on the line A-A ofFig. 4; Fig. 6 is a detail showing in perspective the hanger orsuspensory device by which the jack is fastened to the automobile Uillustrating in perspective the axle-rest or block.

The body part a of the jack comprises the bar or shaft 1) and the twoend-pieces c, d, hinged thereto. Each end the bar I) is formed with anoffset or spoil der c, f. The end-piece c is provided'wi h it air ofarms 9 between which lies one end of the bar 5. A hinge-pin k passesthrough the arms 9 and the bar 6; and the end-piece a provide and conisfree to swing on this hinge-pin h. The

head portion of this end-piece c is formed with ashoulder e which coactswith the shoul JCT e so as to limit the relative movement of theend-piece c-and the bar 6.

Similarly the end-piece d is formed with a pair of arms 9 through whichand the bar I) there is passed a hinge-pin 72. on which the The latteris end-pieced is free to swing. formed with an ofi'set or shoulder 7"which coacts with the shoulder f so as to limit the i of the end-pieced.

there is formed a hole 'v Patented May 23,1916, 3,540.

end-piece d is curved "upwardly at its outer end i, in which there ismounted free to turn a post 7 which is forked and between yoke portion)of which there is rotatably-fastend a wheel m so that this wheel-m isfree to turn after t emanner of the caster-wheel commonly used incultivators and the like. -Through a hole 0' in the head pa'rtof theother end-pieces there is passed an eye-pin n the lower end or headedand the formed with an eye e upper end it of the eye-pin n is with thelower end of a p e lower end of a second plate 9 1s similarly engagedwith the upper end n of the eye-pin n and the upper end 9. of this plate9 is bent toward the plate 0 so as to form ahook. A bolt r passesthrough the two plates 0; g, and, by tightening the nut s the 'twoplates drawn closely toward each other.

engaged At one side of the bar 6 there is fastened may be ectsdownwardly from the axle-restor I block o. The top or upper face of theblock '0 is formed with a depression 12 shaped so as to receive anaxle-end 4- In the biock '1) through which passes the leg 10 of a hookto. The lower end of the leg w is threaded; and upon this threaded end;there is screwed a nut as. Between the nut in and the bar b there isinterposed a washer-plate :0. Near each end of the bar I) there isformed a funnebshaped hole y" and, over this hole 3 and the arms 3,therelies an inverted U-Bhaped Was er-plate 2. Through the hole y andthe pla 2 and between the arms g, (9) there panes a lifting-screw 2 withwhich is engaged anut 3. The lower end 2' of the screw 2 is hook-shaped.

The operation of the device will be readily The lower flange of thechassis or frame whereupon the nut s is screwed up on the A, bolt a soas to fasten these two plates 0, g, together and to secure the hanger orsuspensory device firmly to the frame 5. The nut w is then turned untilthe hook w is firmly engaged Withthe axle-end 4 and locks the samesecurely in place. Thereafter the nuts 3 are turned until the end-piecesc, d, are

forced into line with the bar I). The automobile may then'be moved,resting upon its own three Wheels and the caster-wl1eel m.
